I have heard that justcoin has a pretty nice gateway implementation and it is open source

https://github.com/justcoin/snow

I'm not a website programmer so have been procrastinating delving into this. If anybody has the right experience, it could be a very simple matter to customize it for different altcoins. I'm not doing the gateway to make money, so no need to keep track of fees, etc. My motivation is more long term as a significant DTC owner and XRP owner, it is in my interest that they both do as well as possible.

Changed the title.

Ripple is still in beta release, but about $1 million USD per day is being traded there, so that's pretty real.

James

about how long will this take to catch up, been up all night, but want to make sure I got my aliases or reregister them...

0.4.6 is just 0.4.5 with new data files

It went backwards?!
24168 disappeared

I understand that. That is why I said to reprocess. Rewind the tape and reprocess all the blocks with a version that doesn't have the bug. Maybe all transactions are preserved!

Just got next block

24168      6483973064837388393      12/25/2013 10:46:48 AM   
20      1'418'699 + 193      2'560 B   
1      4525221562411617061      319 %

Large fee, is that legit?

James

Is it possible that a fix like changing 32bit signed int to long and then reprocessing all the blocks from before the overflow will properly preserve all the transactions made?

James

also stuck on 24167, 7 peers and getting new one every 10 seconds or so.

I lost all my aliases, but I still see the transactions that charged me for them?

James

0.45 almost caught up, but already past the tainted block
It seems transactions are preserved, but a bunch of aliases I did seem to be missing
Is there a point in resubmitting all the aliases, or will all this get rewound back to the tainted block?

James

Does this mean we don't have to reconstruct everything manually after the corrupted block?

James

It's a good thing I haven't started the NXT market within ripple yet. Once inside ripple, you can easily transfer to any currency, including BTC. Irreversible.

Pretty scary for a NXT newbie like me. If history is repeating itself, how many times did this happen to BTC?

Also seeing some negative numbers. Maybe we found out the cause of the problem?!

James

I guess its possible this exploit would have been there without the Ddos. Maybe Ddos was a diversion to give him time to cashout the illicit NXT?

James

Ddos attacked made 1 second last anywhere from 1 second to many minutes. This would cause all sorts of unexpected race conditions in the software. Just imagining the issues of different nodes trying to reconcile what is what when the heartbeat was different for every node hurts my brain, I am amazed it was able to pick up the pieces and continue to run.

Not sure if the integer overflow was an accident or a malicious hack, but there were a lot of giant fee generating transactions by that account. Probably saw the millions of NXT he was getting and got greedy and went past 2^31. Good thing signed ints were used! Otherwise he could have gotten away with it.

Who could have predicted such an attack on innocent little NXT, still only one month old?

James

Datacoin is the first of hopefully many. I want to get as many altcoins actively traded within Ripple. It is a functioning distributed exchange that already implements colored coins.

The hardest part of getting an active market is finding an issuer that the traders will trust enough to trade with. The transactions happens in a few seconds and as long as things stay inside of ripple, the distributed ledger keeps track of everything.

The only external interface is the so called gateway. That's just a fancy term to mean a way to deposit/withdraw the thing being traded. Just a matched pair of transactions.

Deposit: altcoin -> gateway acct, ripple altcoin -> depositor's ripple acct
Withdrawal: depositors ripple acct sends ripple altcoin to gateway acct, gateway sends actual altcoin to altcoin wallet.

By doing all the trading inside of ripple it avoids any transfer fees a coin might have. Of course, ripple has the provision for gateways to charge a transfer fee, but I am a strong advocate of frictionless trading and the markets I make are in issues without transfer fees. There are no commissions since it is a distributed peer to peer trade.

By having each altcoin's key moderator be the issuer of the ripple version, it instantly becomes something each community can get behind. No more relying on small exchanges, or begging for the larger exchanges to list your altcoin. I am working on getting a fully automated gateway package so a new altcoin can be supported very quickly and minimize the effort required for the issuer.

I am just me and can only do so much, but I have prepped the ripple community to help out and they are eager to welcome new ripplers.

I would be happy to be the contact point for getting new coins supported.

James

msin,

Don't worry, that didn't actually happen, if it was after block 24179.

James

So everyone is doing things and it will all be like it never happened? Due to distributed nature no way to stop nodes from going on as if nothing is wrong. Seems that an emergency stop mechanism might be a good thing. BCNext could probably figure out how to implement a "ctrl-S" on the blockchain...

So, we need to stay up until new client with fix comes out so we can reregister aliases. Contact all sellers and have them resend the NXT. Should dgex.com be warning people?

In the future when there is more and more functionality and data in the blockchain, this sort of thing becomes a bigger and bigger nightmare. Why is everybody so calm about this?

James

User705,

Luckily, I got the NXT direct from reputable source, but if this means thousands of transactions will have to be redone, wouldn't it be better to somehow stop things?

I also registered a bunch of aliases. I suppose those would be up for grabs when 24180 is fixed?

I would hope only the tainted blocks would have to be redone. What about all the people with dgex withdrawals pending? What a mess.

Tell me this won't require massive manual cleanup.

James

I am a bit confused. Will transactions after 24180, eg. everything happening now, be properly reconciled into the new corrected blockchain?

If not, what happens to people who bought NXT since 24180?
